Kristen Stewart has admitted that despite the risk it posed to her and her career, appearing topless in her new film 'On The Road' didn't bother her one bit.Speaking to MTV News, the Twilight Saga star said that thanks to director Walter Salles and the environment he created on set, she rarely felt frightened or nervous when it came to her on-screen nudity, or any of the other risqué scenes in the Jack Kerouac adaptation.Whilst at the Toronto International Film Festival she told her Mtv interviewer, "You can do no wrong with [Salles]. He puts so much inside of you. In the four-week rehearsal process, it was okay to ask any question, to bring up any story, to really overanalyze everything and intellectualize everything."Stewart, who is no stranger to getting close to directors and 'letting them get inside you', particularly Rupert Sanders, also revealed that the reason why it was so easy to embrace the role of Marylou, topless and drug-taking scenes and all, was that she was so keen to explore the audacity of the Kerouac's semi-autobiographical world. She went on to say, "I don't want this to be misconstrued in anyway, but you do want to get as close to an experience as you can. Anything that feels guarded, in this particular movie especially, would just be so against the spirit of it."On The Road has already been released in much of Continental Europe and will be released in the UK and Ireland on October 12th. The film will be given a limited release around America starting on December 21st.
